How do unicellular respond to their environment?
they respond to their environment by using their special sensors.for example, euglena detects light using the special sensors to feed it self.
How do the eye spot and chloroplasts work together to help the euglena survive?
"The eye spot is a photo receptor. It alerts the Euglena to the presence of light. The chloroplast uses light to carry on photosynthesis. While the Euglena is in the presence of light it is making food. The Euglena also can eat food like other Protists if there is no light." quoted by ATP-Man (http://answers.yahoo.com/question/index?qid=20080114172048AAK4szq)
What can ocelli detect?
Tiny eyes (also called ocelli) that can detect light and dark are located on top of the spiders cephalothorax. They also can detect different wavelengths and intensities of light.
What do your suprachiasmatic nuclei help you to detect?
light
What characteristics in living organisms helps them to detect their environment?
shelter
What is the significance of an eyespot in the cell of Euglena?
To detect light
What plant like protist has an eye spot to help them detect light?
A euglena.
Does an euglena have eye spot?
Euglena also have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food. The color of the eyespot is red.
What structure do euglena have that is sensetive to light?
Euglena use an eyespot to detect light. An eyespot is a dark spot on their body. They cannot see the world around them but they can see light. The eyespot is located anywhere on their body but usually near their flagella. A flagella is a whip-like strand that euglena and other organisms use to move through the water. Euglena are producers and they make food through photosynthesis so they need the light.
What does the eyespot do for euglena?
The photoreceptive eyespot allows the organism to orient and swim toward light, whichh is helpful for photosysnthesis. Interesting side note: in Euglena, theree is a dark pigment patch just underneath the eyespot. This means that Euglena is detetcing darkness and swimming away from the dark and thereefore inot the light. Without this pigment patch, the eyespot could not function because the cell body is essentially transparent. I'm not sure if this is the same for Chlamydomonas, but I would expetc so.(From: www.gadgetking.com/trends/eyespot+euglena)
The euglena's red eyespot is used for?
so it can find the brightest part of its environment it is not a true eye like ours all it does is detect light
What is unique about the way a euglena obtains food?
A euglena can be both a producer and a consumer. Its red eye helps it detect light for photosynthesis. If no light, then it captures food. Hope i helped::)
What function might the stigma of the Euglena serve?
The students are planning to write labels for their diagram, explaining how each part contributes to the function of the euglena. Which label would be most appropriate for the chloroplast? Responses "This structure helps the euglena obtain minerals from its environment so that it can perform life functions." "This structure helps the euglena obtain minerals from its environment so that it can perform life functions." "This structure helps the euglena remove food wastes from the cell after their nutrition has been used for life processes." "This structure helps the euglena remove food wastes from the cell after their nutrition has been used for life processes." "This structure helps the euglena use up energy it has stored in the process of building new cell parts and growing."

What is the light sensing organ in Euglena?
actually there is eye spot in Euglena which help it in the detection of light
How lizard eyes work?
It helps to detect light
What is the spot of chromatin?
The spot of chromatin in a euglena is called the eye spot. It allows the organism to detect light so it can move towards it so it can photosynthesize more efficiently.
Why is a sensory structure so important to the euglena?
Euglena have a primitive organelle called the eyespot which detects light.
